DTZ1737 is a wall mounted three phase four wire multifunction energy & electric meter with backlight LCD display.
It is a smart energy manage meter with software platform for a total solution in smart buildings, factories, schools, hospital etc... Built-in wireless NB-IoT communication modem (more options as GPRS/3G/4G,LoRa) can collect the energy data from the meter and transmit remotely directly to the server platform for energy data analysis.
Hop smart energy meter is adaptable for time difference in different countries, even keeping same time zone with the software platform.In the case of no network, the data can be still stored in our meter one year (depends on how much data) until the network communication recovers.
Functions
1. Metering & Measurement:
Current, voltage, power factor, active power, daily energy, energy consumption…
2. Communications:
Built in NB-IoT modem with plug-and-play design.
More options: GPRS/3/4G, LoRa, etc.
Transmitting data directly to the server platform.
3. Remote Power on/off Switch Control:
Relay built in answers the Switch on/off command from the server platform to remotely control the power on/off.
4. Data Storage: Energy data stored in the modem traceable and retrievable in case of NB-IoT or other network disruption. Storage up to one year to avoid data loss.
5. Display: Backlight LCD display screen with various status indicators.
6. Energy Freezing:
Time freezing, instantaneous freezing, daily freezing, contract freezing, and periodical freezing)
7. Event Record:
Abnormal data: voltage, current, active power, demand, zeroing, trip, time calibration, programming, power loss, etc.
System Diagram
With built-in wireless communication modem, NB-IoT modem, the meter can transmit the energy data directly to the server platform. The communication modem is flexible and changeable according to the local network situation. Metering and transmission two-in-one design is an excellent combination with advantages of cost saving, simple construction, quick deployment.
Features & Advantages
1.Simple Construction:
Robust design with communication modem built in the meter.
2.Save cost:
Electricity meter + gateway two-in-one, no need external DTU device, no need RS485 wiring, saving equipment, materials and labor costs.
3.Data Storage Retrievable:
With great capacity, the NB-IoT modem can store energy data at least 2 months to avoid data loss in case of network gone.
4.Remotely upgradable:
The internal program of communication modem can be remotely upgraded, which is convenient for aftersales system maintenance.
5.Automatic reading without manual:
Remote reading of meter data through communication modem to reduce on-site labor costs.
6.Flexible Communication Selection
The communication module can be selected according to the local network mode, for example, NB-IoT, GPRS, 3G, 4G and LoRa can be selected to achieve a matching network connection.
7.Two payment solutions available: pre-payment and post-payment.

Q: Do you have APP for three phase four wire energy meter?
A: Since different areas' clients have different using habit, so APP is always customized for clients according to the developing instructions clients give.
Q: Can the smart energy meter support wireless communication?
A: Yes, there is communication modem built in the meter, such as 4G, GPRS, 3G/ NB-IoT, Lora, etc.
Q: Can you put our logo on the 3 phase 4 wire smart energy meter?
A: Yes, we can put your logo on the meter, data collector(concentrator) and system software.
Q: Can I confirm whether the communication is successful through the indicators light on the meter?
A: Yes,From the two status indicators of the meter,you can identify the communication status of the meter network; When the green light flashes, the communication module works normally.
Q: If the load of 100A needs to be switched off, can you achieve it with your electricity meter?
A: 100A load can be pulled, but the circuit breaker (outer pull) needs to be configured, and the 60A meter can be pulled by the internal relay breaker.
Anti-collision bag + individual box + outer carton + 5 layers of cartons on pallet (if client has other air/sea shipping packaging requirements, we also can meet)
We have stable and reliable cooperating shipping agents in Chengdu, Shenzhen, Shanghai which can offer professional service and reasonable price.
